Advances of the Remediation Technology of Soil Contaminated by Polycyclic Aromatic Hydrocarbons

Polycyclic aromatic hydrocarbons are carcinogenic,teratogenic,mutagenic micropollutants,concerns over their adverse human health effects have resulted in extensive studies on the remediation of soils contaminated by PAHs. This paper aims to provide a review of the remediation technologies specifically for PAH-contaminated soils. The remediation technologies including bioremediation,phytoremediation,solvent extraction,chemical oxidation,electrokinetic remediationand thermal treatment are discussed in this paper.
